Hindi ko naman ma-worry yung occasional amoy ng alcohol sis, lalo na kung well-ventilated ang space mo, pero since madalas talaga ang spraying mo sa room, I'd really suggest checking with your OB just to be sure kasi every pregnancy is different and sila lang ang makakasabi ng tama para sa iyo specifically. A few of us moms try to open windows while disinfecting or use it sa specific areas lang para mabawasan ang exposure, pero since ikaw eh heavy user talaga, mas maganda na marinig mo directly from your doctor ang safest approach para sa peace of mind mo.
